How is the overall average on MyScol calculated?

For each student, it is possible to calculate the average of the different assessments of a given subject. Ratings can be scored out of 5, 10 or 20 and have coefficients of different


To calculate the average, MyScol Bring back the notes Out of 20.


That is, if you have grades on 5, 10, 20 or 30, the formulas to apply are:

Note from the student/ 20= (Initial student note / Score Scale) *20* Coefficient


And


Average of student/ 20= Sum of notes out of 20 / sum of coefficients

Presentation on an example


A student's grades for a subject X are:
2/10 with Coeff 1;
9/15 with Coeff 2;
27/30 with Coeff 3


What happens if you bring the notes out of 20?

The notes become:
4 /20 Coeff 1;
12 /20 Coeff 2;
18 / 20 Coeff 3


The calculation to be made is then:


m = (4 × 1 + 12 × 2 + 18 × 3) / (1 + 2 + 3)

m = 82/6

m = 13.67
